“…the Sylvester matrix of f and g. If the resulting triangularized matrix is arranged as a right upper triangular matrix, the bottom most non-zero row corresponds to a gcd of the polynomials f and g. As a first step we generalize this method to the case of r univariate polynomials with r ≥ 2. Such generalizations have been done before (see [5], [2]). Those, however, resulted in bigger matrices.…”

“…Differently, it is shown below that for p > 2 the matrix R is not a resultant matrix as it can be singular even if the polynomials a(rjz), 0 ≤ j ≤ p − 1 have no common factors. Extensions of the classical resultant theorem for more than two polynomials (p > 2) are established in [1,13], but they employ rectangular generalized resultant matrices. πi z) and a(e 4 3 πi z) are pairwise relatively prime, it is easily found that the corresponding 9 × 9 matrix R is singular.…”

“…The above suggests that the resultant set may be used for the evaluation of GCD and the resultant properties expressing these links are summarised below [10,12,13]. The Sylvester resultant result stated above is central in establishing a number of important computational procedures for the GCD of many polynomials.…”
